Hydraulic gear pump on motor with measuring main gear pair - has secondary gear pair, coacting with main one, with one pair acting as pump, and another one as motor
Hydraulic gear pump on motor with measuring main gear pair - has secondary gear pair, coacting with main one, with one pair acting as pump, and another one as motor
There is at least one secondary gear pair (39), coacting with the main one. One gear pair operates as a pump, while the other one forms a motor. The outlet side pressure chamber of the main gear pair is coupled to the inlet side pressure chamber of the secondary gear pair. With at least one gear pair the axial spacing (aS, aH) is variable. ADVANTAGE - Variable delivery vol., adjustable servo delivery, and small sealing regions at low-cost mfr.
